Does your remote setup work on SSB? Notice that your remote K3 radio must be configured in CONFIG or MENU to use mike audio from the back for TX.

My Remoterig setup works running audio cables from K3/0-MINI Spkr and Mike to my pc Mike and Spkr. In order not to transmit Windows sounds I use an USB sound card, but that is not required. My strapping of the Remoterig boxes is done as described in the manual.

Some standard failures: Have you selected the right audio devices in WSJT-X? Hopefully you have not turned down audio volume in Windows Volume mixer. Are you sure WSJT-X does not pick up RX sounds from the loudspeaker?

There is an USB audio device on the K3/0, but it can't be used as input and output is reversed. I don't think you can fix it or an USB input device can be made into an output device using a Virtual Audio Cable. Instead ask Elecraft to fix this error.

However Mike and Speakers on the left side works for digital remote if you reverse the two cables between the K3/0 and your pc.

As your radio and control site are in the same house you should not have many problems if radio and control are on the same LAN. If you want to use a pc at the radio you may use COM1 as Mitch has written.

I manage my 13,8 V at the radio site with a Rigrunner 4005i Wifi: www.westmountainradio.com/product_info.php?products_id=rr_4005i so I can check voltage and current and even power cycle both my K3S and the RRC 1258 should I need to. That need has not happend yet, but nice to be in control. The Rigrunner has built in fuses and over voltage protection. Wifi might be an advantage during thunderstorms.

You could use a Rigrunner 4005i Wifi to power on/off you KPA1500 with 13,8 V to the REM port.

BTW the KPA1500 can be remoted via its ethernet port. I would do all 3: 12 V to REM, Rigrunner and use the ethernet port.

Power on and off seems easy, see page 23 of the KPA1500 operators manual:

Remote Operation...Additionally, the rear panel REM jack enables remote on and off switching: When 12 VDC is applied to theKPA1500 REM connector, the amplifier is turned on. Removing 12 V turns the amplifier off. Less than 1 mA isrequired. The 12V DC OUT jack on the K3/K3s can be used for this function.

>Instead of trying to run wsjt-x at the control site, I bought a NUC to put at the radioWhy are you making it so difficult for yourself to run WSJT-X? Just connect your Elecraft K3/0 Mini to your pc at your control site and run WSJT-X.

Unfortunately there is an error in the K3/0 Mini, as input and output (mike and speakers) are reversed both in the USB audio device and the two 3.5 mm Mike and Speakers ports at the left side. This means that the USB audio device can't be used, but the Mike and Speakers ports works for WSJT-X well when connected reversed by wires to your pc. I do my FT8 in this way.

I suggest more owners of K3/0 Mini make a request to Elecraft for having this error corrected at least in the USB audio device.

Regarding COM2 on the rear panel of the RRC-1258 it should be connected to the RS232 port on the K3S (or P3), so the COM2 of the Remoterig box is in use. However COM1 on the front panel of the RRC-1258 is not used by Remoterig and can be used for your KPA1500.

As I understand the question the problem is the same as I have. At the radio site there is a 'local' pc which should be able to control the K3 via CAT whenever the RRC is not in use and that without switching cables. After all the remote operator can't switch cables. The RRC (COM2) and the pc is connected to the P3 serial DB9 connector (RS232) through a Y serial cable. This does not work for me.

Mitch, is your idea to connect the 'local' pc at the radio site to COM1 of the radio RRC and to connect the radio RRC COM2 to the P3 as usual? Then the radio RRC is working as a logical Y cable if set to Mode 7?

As far as I know a Y serial cable only works in one direction, that is when one master sends to several slaves, but I would like to know if anyone has a solution for a Y cable at the radio site.

Sounds like an internet problem with variable delay either at your control end or at the radio end. May be a big down or upload is running? You can get an indication of your internet connections by checking ping time with www.pingplotter.com/download

Your ping times to your remote site seems quite OK, mostly under 100 ms. The few spikes to 150-200 ms should not be much of a problem if you configure 'Advanced settings' and 'Keyer settings' in the RemoteRig boxes. Values for 'Keyer settings' is in the manual and if I recall correctly the delay should be similar to the ping time so try 100 ms. Here on this forum Mitch, DJ0QN has given recommendations for 'Advanced settings' for 3G. However your 4G/LTE is much better than a 3G connection, so I don't think you need to increase 'Advanced settings' that much.

I have set up a PingPlotter checking from my QTH here in Denmark to your remote site and I get quite stable 200 ms ping time during almost an hour with only 2-3 spikes to 300 ms. That is fine as crossing the pond often adds about 100 ms.

Make sure your 4G/LTE router is set up for '4G only' so it does not drop down to 3G once in a while.

I have experienced longer ping times about once every minute when I am on WiFi. As WPA renegotiates encryption key once every minute I believe this may cause a delay. I found this using PingPlotter, but it has not been a problem for me

It is possible to make the RemoteRig boxes cope better with dropouts by adjusting 'Advanced settings'. Have a look on 'Keyer settings' also as you have problems with CW.

I have not changed "UDP cmd min-data-size". I noticed my problem some years ago and after checking, reboot and power cycling both RRC I ended up by power cycling the IC-7100 radio box (13,8 V off and on) and after that no more "UDP cmd Error" and the IC-7100 control panel could power on and start working. I may have had to power cycle the IC-7100 radio box about 3 times the last 5 years, so it is not a frequent problem. I have never seen similar "UDP cmd Error" with my K3 - K3/0-Mini setup.

On my setup with an IC-7100 and RRC boxes I have experienced UDP cmd status: error a few times during the last 5 years. In my case the IC-7100 radio locks up which can be overcome by power cycling of its 13,8 V. Restart of the remote RRC does not help. As I have a RigRunner 4005i see www.westmountainradio.com/product_info.php?products_id=rr_4005i power cycling of the radio is easy to do remote.

You need to get the audio to and from you control head of your IC-7100 from and to your local control pc where you have WSJT-X running. I use a Signalink USB for that. SignaLink to the Mic jack in the IC-7100 front panel using a standard Ethernet cable. My SignaLink is strapped accordingly by comparing the pin output of the Mic jack and the SignaLink, see www.tigertronics.com/sl_wirebm.htm#ICOM
